1. A large channel through which large blood vessels pass carrying blood to and from the bone marrow.






2. A joint in which the bones are united by cartilage; also called an amphiarthrosis. Only a slight rocking motion is permitted between the bones.






3. The skull bones that do not surround the brain. External bones: the incisive bones - the nasal bones - the lacrimal bones - the maxillary bones - the zygomatic bones - and the mandible. Internal bones: the palatine bones - the pterygoid bones - the v






4. The end of a long bone; each long bone has a proximal and distal _____.






5. The bones of the limbs (appendages)






6. Paired sesamoid bones in the legs of horses; located in the large digital flexor tendons behind the fetlock joints.






7. The concave articular surface of the scapula; the socket portion of the ball - and - socket shoulder joint.






8. The eardrum; a paper - thin connective tissue membrane that stretches across the opening of the external ear canal into the middle ear.






9. The shoulder blade; the most proximal bone of the thoracic limb. No bony connection exists between the scapula and the axial skeleton.






10. An immovable fibrous joint - such as the suture that unites most of the skull bones.






11. Skull bones that are external bones of the cranium; form the dorsolateral walls of the cranium. They are large and well developed in dogs and cats - but small in horses and cattle.






12. The growth plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. They are areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full adult






13. The joint movement that increases the angle between the two bones.






14. The bones of the neck portion of the spinal column.






15. The bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone; in the living animal - it contains the external ear canal.






16. A pair of large holes in the pelvis located on either side of the pubic symphysis; the role seems to be to lighten the pelvis because no large nerves or vessels pass through them.






17. The process of a vertebra that forms a synovial joint with an adjacent vertebra.






18. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






19. Also known as the spinal column; the collective name for the cervical - thoracic - lumbar - sacral - and coccygeal vertebrae.






20. The paranasal sinus in the ethmoid bone of horses and humans.






21. Another term for the diaphysis of a long bone.






22. Bony arches below and behind the eyes of common domestic animals; in dogs and cats they form the widest part of the skull. Made up of the rostral - facing zygomatic process of the temporal bone joined with the caudal - facing temporal process of the






23. A skull bone that is one of the internal bones of the face; forms part of the nasal septum.






24. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






25. A bone of the sternum.






26. A band of fibrous connective tissue that is present in and around many synovial joints; connect the bones of the joint to each other.






27. Small cavities within the matrix of some connective tissues - such as cartilage and bone - within which cells are contained.






28. The 'horn core' of horned animals; a process of the frontal bone. The hollow cavity within this process is continuous with the frontal sinus (the paranasal sinus of the frontal bone).






29. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






30. The joint movement that decreases the angle between two bones.






31. The cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally. Also called the pubic symphysis.






32. A bone whose shape does not fit into the long bone - short bone - or flat bone categories. Bones either have characteristics of more than one of the other three shape categories or have a truly irregular shape. Includes vertebrae and sesamoids.






33. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






34. A general name for a lump - bump - or other projection on a bone; can be articular processes or nonarticular processes - which are usually sites where tendons attach.






35. The breastbone; a series of rodlike bones called sternebrae that form the floor of the thorax.






36. The large metacarpal and metatarsal bones (III) of the horse.






37. Also called a spheroidal joint - it consists of a spherical joint surface (the ball) that fits into a closely matching - concave joint surface (the socket). Examples: shoulder and hip joints. Capable of all synovial joint movements.






38. Skull bones; external skull bones of the face. These two small bones form part of the medial portion of the orbit of the eye and house the lacrimal sacs - which are part of the tear drainage system of the eye.






39. The large process on the proximal end of the ulna that forms the point of the elbow; the site where the triceps brachii tendon attaches.






40. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






41. A beak - shaped process at the proximal end of the trochlear notch of the ulna; when it fails to unite with the ulna - an ununited process can cause the elbow joint to become unstable - leading to lameness.






42. Spongy bone; a form of bone composed of a seemingly random arrangement of spicules of bone separated by spaces filled with bone marrow. Appears spongelike to the naked eye. Found in the ends of long bones and the interiors of short bones - flat bones






43. One of two small sesamoid bones located in the proximal gastrocnemius muscle tendon just above and behind the femoral condyles of dogs and cats.






44. A lateral - projecting process of a vertebra.






45. The collective name for 37-38 bones of the head; it houses the brain and all the special sense organs.






46. The last - most caudal sternebra; the _____ process.






47. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






48. The most proximal bony structure of the pelvic limb; also known as the os coxae. Attaches to the sacrum dorsally at the sacroiliac joints and forms the hip joints with the heads of the femurs.






49. The group of vertebrae located dorsal to the thoracic region; noted for their tall dorsal spinous processes.






50. The bony roof of the mouth; the division between the mouth and the nasal cavity. Made up of portions of the maxillary and palatine bones.
